// 01 — What we do

CTO firepower on-demand

Stop guessing. A senior CTO embeds in your Slack, standups and board meetings 2-3 days/week and owns technology outcomes.

We hire your first 5 engineers, set career ladders, kill micromanagement. Build a culture that ships without the CTO in the room.

// 02 — About PT-CTO

We are the CTO you can't hire full-time yet.

PT-CTO (pt-cto.com) was founded by ex-CTOs from SaaS unicorns and fintech scale-ups. The idea is simple: world-class technology leadership shouldn't cost $320k/year + equity from day one.

We act as your Part-Time CTO: part strategist, part architect, part coach. We have led teams of 4 to 120, migrated monoliths at 2am, passed SOC2, HIPAA, PCI-DSS, and sat in boardrooms explaining why rewriting everything in Rust is a bad idea.

✅ 14 senior CTOs, no juniors
✅ US + EU timezones overlap
✅ Hands-on: PRs, ADRs, RFCs
✅ Vendor-neutral, no kickbacks

Our manifesto: “Clarity over cleverness. Boring tech that scales. Teams over heroes. Ship every week.” If your roadmap slips, churn rises, or engineers quit — we fix the system, not just symptoms.

FAQ
Ask a question
What is a Part-Time / Fractional CTO?

A senior technology leader working 2-3 days/week. You get strategy, architecture oversight and team leadership without full-time cost. Perfect from pre-seed to Series B.

How fast can you start?

Discovery call in 48h, audit kickoff in 7 days. Embedded leadership from week 2. We work in your timezone (US + EU overlap).

Will you write code?

Yes — but wisely. We review PRs, write ADRs and critical prototypes, but our job is to make your team ship without us, not to become a bottleneck.

Do you help with fundraising DD?

Absolutely. 80+ technical due diligences passed. We prep data rooms, answer VC tech questionnaires and join partner calls.

What stack do you cover?

Node, Python, Go, Ruby, React, Next.js, AWS, GCP, Azure, Kubernetes, Postgres, Kafka, LLM/RAG stacks. Vendor-neutral advice.

Can you replace our CTO or VP Eng?

We can act as interim CTO, coach your current lead, or hire and onboard your full-time CTO in 90 days with a clean handover.
